so i recently got my turbo setup done and running and have been driving on it for a couple days now. I have the hks ssqv BOV which the functionality is perfect and i love it. the only thing that is starting to bug me some is the whistle is makes when it blows off. I have heard it without the insert and it is more of a whooshing noise which is discreet and just a nicer sound. i just want to make sure no one has done this and run into problems with the insert out. any input that is POSITIVE towards the subject is appreciated. if you wanna get on here and call me dumb for getting that BOV then go ahead... it was free btw as a demo from the shop.
